Orthodontic considerations for impacted and ectopic teeth.

This review article describes the changing approach to the management of various impacted teeth. Currently, more third molars are being retained, and it is likely that more patients will develop impactions than a generation ago because of non-extraction orthodontic treatment plans. There are still valid reasons for the surgical removal of selected third molars during the teenage years, during which time impaction can be anticipated to avoid the higher rate of morbidity associated with later removal. Palatally-impacted canines (PIC] can now often be managed with interceptive and non-surgical approaches, which are attractive options. The various approaches addressed in the literature are discussed.
